Investigators found that the home was set ablaze with gasoline being used as an accelerant.

Deputies learned that a girl in the home had recently ended a relationship with 31-year-old Adrianne Legarde.

The girl and Legarde began dating when the girl was 15 years old and Legarde was 29 and engaged in a sexual relationship during their time dating one another, according to the Sheriff’s Office.

It was also learned that Legarde made threats to the girl and her family after their breakup, and evidence was found, linking Legarde to the arson.

When investigators found Legarde, she admitted to the relationship with the minor and was arrested on charges of aggravated arson and felony carnal knowledge of a juvenile.
